Step-by-Step Solution

Answer

The distribution is non-symmetric and right skewed.

Step 1: Given Information

The given graph is :

we have to state whether the distribution is symmetric, right skewed, or left skewed. 

Step 2 : Explanation

If the shape of any distribution is divided into two parts, one of which is the mirror image of the other, the distribution is said to be symmetric.

The graph in question cannot be divided into two equal halves, one of which is a mirror image of the other.

As a result, the graph's shape is non symmetric.

The longer tail of the distribution lies towards the higher values of the variate, and the mean is greater than the median.
